The attempt of this article is to collate as many Buddhist Goddesses as I could
    and Hindu Goddesses that are identical and show the reader how similar both systems
    are at the core, almost identical, with very marginal visual and name variations.
    I have always believed the differences in so called Hindu and Buddhist thought is
    complete semantics, There may be marginal variations as all schools of thought in
    Hinduism too have even within the faith. There is a trend of late by both sides
    to pull the two streams apart for mostly political or ego centric, reasons of exclusive
    identity. Hopefully this collation of goddesses would show the reader the similarities
    are far greater than the differences.
    1.Goddess Samantabhadri; (In sanskrit Samanta + Bhadri Tibetan; Kuntosangmo) 
    The Primordial mother of all Buddhas.
    Samanta: Countless, infinity, end of space, being on all sides or all pervasive,
        countless.
    Bhadra: Gentle lady
    Guru and yidam - Primordial Mother of all the Buddhas is also considered an analogue
    of Prajaparamita.
    Samantabhadri is the consort and female counterpart of Samantabhadra / Kuntuzangpo,
    the primordial Buddha of the older schools of Tibetan Buddhism. They are usually
    shown in sexual union (yab/yum in Tibetan), the blue male figure and white female
    figure embracing each other in lotus position.
    Samantabhadri is sometimes shown alone, in which case she is seated in lotus posture
    with her hands in meditation posture in her lap. Samantabhadri is always shown naked
    (as is her consort) to demonstrate the unadorned nature of Absolute Truth, the emptiness
    of all phenomena. She is in some senses an analogue of Prajnaparamita. A near equivalent
    of the New Translation schools is the dark-blue Vajradhatu-ishvari, shown in union
    with consort Vajradhara as the yab-yum Vajradhara / Vajradhatu-ishvari.
    All Hindus know that Shiva has a blue body, has a fair wife Durga, and a dark skinned
        wife Kali . The symbolism is a shiva linga where the phalic symbol (shiva) is embedded
        in the yoni ( the circular stone around it, in an eternal sexual union. Hence you
        will see many later descriptions of Tara come close to Parwati , Shivas second wife
        who is an emanation of Sati who is Shivas first wife. Durga in Hinduism is the feminine
        force or Deity that manifests from the shunyatam or the ether of empty space from
        which everything arises.

    2.Goddess Prajnaparamita (Sanskrit; Prajya + Paramita)
    Prajya : Lofty, High, Lasting , Abundant
    Parameter: Complete attainment, Trancendent Virtue, Perfection in.
    Guru and Yidam - Mother of all the Buddhas.
    Prajnaparamita embodies the bliss/emptiness that gives rise to all phenomena --
    hence her honorific title as Mother of all the Buddhas. She usually appears as a
    tranquil seated figure clothed in silks; her body is gold in colour, and she has
    one face and four arms.
    Her name means 'Perfection of Wisdom'; in Tibetan she is also known as Yum
    Chenmo, or 'Great Mother'. She is closely associated with chöd practice.
    Embodies bliss and emptiness and gives rise to all phenomenon? This is the identical
        description of Durga Ma in Hinduism.

    3.Goddess Palden Lhamo (Sanskrit ; Sri Devi)
    Dharma protector - wrathful protectress of Tibet
    Palden Lhamo (whose name translates as "Glorious Goddess") is the
        only female dharma protector common to all four schools of Tibetan Buddhism. 
    She is very wrathful, and rides her mule through a sea of blood, surrounded
    by wisdom fire. She is dark blue and has one face with three eyes; she wears a sun
    at her navel and a moon at her crown, and over her is a peacock umbrella (a traditional
    symbol of protection). She is variously depicted, but her most common forms are
    two-armed and four-armed. There is also a system of divination by dice associated
    with her. She is sometimes considered cognate to Sarasvati or Tara, but is at the
    same time a wrathful emanation of the peaceful goddess Sri Devi. Please note
        the skulls on her crown and the slain human below.

    of Shiva, who is credited for making Shiva cross over from a state of constant meditation
    to engaging in the world)
    5.Goddess White Tara (Sanskrit: Sitatara; Tibetan: Sgrol-dkar) 
    Sometimes called the Mother of all Buddhas
    I don't have to translate this, I think all Hindus know who Sita is.
    6.Goddess Blue Tara (Sanskrit: Ugra Tara; Tibetan: Ral chig ma,)
    Also called Ekajata, Black tara is also called Ekajati
    Ugra; Furious, Fierce, Terrible, Passionate
    Ekajata; One who is the bank of the river, One who is the protector
        , One who is the dancer.
    7.Goddess Red tara (Sanskrit; Kurukulla)
    Kuru kulla in sanskrit means the little princess (Kulla) of the kuru
        race 
    Kuru (Sanskrit: कुरु) was the name of an Indo-Aryan clan in Iron Age Vedic India,
    which started in the Early Vedic period and later evolved into a republican Mahajanapada
    state in the later Vedic period. The Kuru clan was located in the area of modern
    Haryana, Delhi and western parts of Uttar Pradesh (the region of Doab, till Prayag
    / Kaushambi) in North India. According to ancient texts, the territory of Kuru clan
    lay between the Rgvedic river Sarasvati and river Ganges and was split into two
    parts as Kuru-Jangala and Kuru Proper.
    
Tibetan Goddess: Saraswati yidam.
     
    
8.Sarasvati Yidam - goddess of learning and the arts
    As the goddess of learning and the arts, Sarasvati (also spelled Saraswati) is in
    many ways a counterpart to Manjushri, the male Bodhisattva of discriminating wisdom,
    and is sometimes his consort. Sarasvati is a peaceful yidam who holds a vina (a
    sitar-like lute) on her lap; she also sometimes holds a text. There is also a Hindu
    deity named Sarasvati with near-identical attributes. She is sometimes associated
    with Palden Lhamo, who may be regarded as Sarasvati in wrathful form. The most popular
    form of Sarasvati is white-coloured, with one face, two eyes, and two arms; however,
    there are many other forms including the white four-handed Sarasvati and the red
    Vajra Sarasvati.
    Tara in Hinduism
    Tara (Devi) (From Wikipedia, the free encyclopedia)
    This article is about the Hindu goddess. For the Buddhist bodhisattva, see Tara
        (Buddhism).
    Sanskrit Transliteration Tārā
    Affiliation ; Devi, Mahavidyas
    Mantra; oṁ hrīṁ strīṁ hūṁ phaṭ (the above is her most important mantra as Dasa
        Mahavidya)
    Also: oṁ tāre tuttāre ture svāhā
    Weapon; Khadaga, Sword
    Consort; Shiva
    In Hinduism, the goddess Tara (Bengali:দেবী তারা মা )(Sanskrit: Tārā, Devanagari:
    तारा) meaning "star" is the second of the Dasa (ten) Mahavidyas or "Great
    Wisdom [goddesses]", Tantric manifestations of Mahadevi, Kali, or Parvati.
    As the star is seen as a beautiful but perpetually self-com busting thing, so Tara
    is perceived at core as the absolute, unquenchable hunger that propels all life
